  • Got stem cells?

    Stem cells are those raw undefined cells that can morph into a new heart, brain, muscle cell.  There is a pool of stem cells throughout your body that is made endogenously.  Stem cells are critical for cellular repair.  There is a horde of dietary supplements sold online that purport to stimulate stem cell production.  Most of the stem cell-inducing dietary supplements being sold offer beneficial ingredients.  A common one is astragalus, an herb that has been shown to promote stem cells in rodents.  [Journal of Orthopedics & Traumatology 2011]

    However, I could not find one stem cell enhancer that contained vitamin A.  The published evidence that vitamin A is required to induce stem cells to differentiate into skin, blood, brain, muscle cells.  [Critical Review Food Science & Nutrition 2015; Nutrients 2014; Development 1994]   2014] Vitamin A also inhibits stem cells becoming cancer cells. [Carcinogenesis 2015]  If you have had a stroke, a heart attack, have scarring in the back of your eyes (retina), or cell damage elsewhere, you should first think of vitamin A, not all these stem cell-enhancement formulas featuring exotic herbs.  Lack of vitamin A may be an overlooked cause of chronic ear ringing (tinnitus).  Obviously, vitamin A may induce stem cells to regenerate hair cells in the ear.

    Just how genuine is the advice provided by makers of these stem cell formulas when they don’t inform you about, nor do they include, vitamin A in their products?
